WILLIAM E. TROUTMAN, OF VANDERGRIFT, PENNSYLVANIA.

MACHINE FOR REVERSING FLASKS AND MOLDS.

Specification of Letters Patent.

Patented Oct. 1, 1907.

Application filed March 4, 1907. Serial No. 360,446.

To all whom it may concern:

Be it known that I, WILLIAM E. TROUTMAN, a citiz'en of the United Statesof America, residing at Vandergrift, in the county of Westmoreland andState of Penn- To this end, my invention is particularly adapted forfoundries where large flasks and patterns are used, the machineembodying my invention being especially constructed for flasks andpatterns of a considerable weight.

With the above and other objects in view, which will more readily appearas the invention is better understood, the same consists in the novelconstruction, combination and arrangement of parts to be hereinaftermore fully described and then specifically pointed out in the appendedclaims, and referring to the drawings forming part of this application,like numerals of reference designate corresponding parts throughout theseveral views, in which:-

Figure 1 is a front elevation of my improved machine, partly in section,Fig. 2 is a side elevation of the same, illustrating a flask in a tiltedor partly reversed position, Fig. 3 is a plan of the machineillustrating the flask thereof in section, Fig. 4 is a perspective viewof a clamp used in connection with the machine, and Fig. 5 is anelevation of a portion of the machine illustrating a slightmodification.

To put my invention into practice, I construct a track way consisting ofstandards 1 and a plate 2, said plate being provided with rails 3 anddiametrically opposed openings 4. Upon the plate\2 adjacent to theopenings 4 I mount guide ways 5 having vertically disposed V-shapedgrooves 6 formed therein the object of which will be presentlydescribed. Adapted to move upon the rails 3 is a car truck 7 carrying askeleton-like structure 8, said car being employed for conveying flasksto and from said machine. Beneath the trackway I locate a hoistingmechanism such as a hydraulic cylinder 9, to the plunger 10 of which isconnected an elevator 11 comprising side arms 12 and 13 having V- shapedguides 14 adapted to slide in the guide ways 5. The hydraulic cylinder 9is suitably controlled and to cushion the downward movement of theelevator 11, I

interpose a coiled spring 15 between the hydraulic cylinder 9 and saidelevator.

The upper ends of the side arms 12 and 13 are provided with two-partbearings 16 to receive the trunnions 17 and 18 of a pattern support 19.The trunnion 18 is slightly longer than the trunnion 17 and upon itsouter end is provided with a spur wheel 19 adapted to mesh with the spurwheel 20 revolubly supported by a bracket 21. carried by the side arm 13of the elevator.

Detachably secured to the pattern support 19 by nuts and bolts 20 orsimilar fastening means is a pattern 22, and adapted to fit over saidpattern is a flanged flask 23, said flask being centered upon thepattern support 19 by diametrically opposed dowel pins 24. The flask isretained in engagement with the support 19 by end clamps 25, said clampsbeing pivoted as at 26 upon the pattern support 19 and limited in theirmovement by pins 27. The clamps 25 are adapted to overlie the flanges 28of the flask 23, and prevent the flask from becoming detached from thepattern support 19 when the same is being reversed. After the flask hasbeen filled with sand or similar material and tamped, aflask plate 29 issuitably secured to the flask, as at 30. It willbe observed that thepattern support 19 is normally a fixture of my improved machine, butshould the same be injured it can be easily removed through the mediumof the two-part bearings 16.

The pattern 22 which is detachably connected to the support 19 can beeasily and quickly changed, and in order that the operation of themachine will be readily understood I will assume that the flask 23 hasbeen properly tamped and is ready to be removed from the machine. tionto raise the elevator 11 to such a position that the pattern support 19will be freed from the car.. It will be seen that the elevator 11carrying the pattern support 19 also carries the spur wheels 19 and 20.I now use a crank handle, motor or suitable mechanism for rotating thespur wheels and inverting the pattern support 19 and the flask 23secured thereto by the clamps 25. The elevator 11 is then partly lowereduntil the flask plate 29 engages the skeleton like structure 8 of thecar. The clamps 25 are then released, whereby the flask 23 will restupon the skeleton like struc- The hydraulic cylinder 9 is placed inopera- 7 ture 8. The elevator 11 is then raised carrying with.

it the inverted pattern support 19. After the pattern support hascleared the inverted flask upon the car, the

car is removed. Another carrying a flask is now placed beneath theinverted pattern support 19, and the elevator lowered until the patternsupport engages the,

ered until the pattern support rests upon the car, as shown in Fig. 1,and then the flask is ready to be filled and tamped. After thisoperation, the flask plate is placed upon the flask, and the operationas first described is repeated.

It will be observed from the foregoing description taken in connectionwith the drawings, that I have devised novel means for manipulating apattern support and flask, whereby the manual manipulation of heavyflasks and patterns is entirely dispensed with. By employing my improvedmachine, the preparation of molds is greatly facilitated, and it isobvious that the machine can be economically installed in variousmanufacturing plants where molds are used for producing articles madefrom plastic or molten material or metals.

In lieu of the spur wheels 19 and 20, I can provide the trunnion 18 witha hand wheel 31, this form of manipulating the pattern support and flaskbeing particularly designed where small molds are to be made.

I do not care to confine myself to the type of hoisting mechanism usedand such other changes in the minor details of construction, as arepermissible by the appended claims, may be resorted to without departingfrom the spirit and scope of the invention.

What I claim and desire to secure by Letters Patent, is:

In a molding machine, standards supporting :1 connect ing plate and acar track carried by the latter, a car adapt:- ed to travel thereon,said plate having diametrical openings on each side of said track,Vshaped guide ways mounted on said plate adjacent said openings. :1hoisting mechanism beneath said plate and a U'shaped elevator supportedthereby, said elevator having side arms slidahly retained within saidopenings, the V-shaped guides upon said guide arms slidably fitting saidguide ways, a pattern support trunnioned in the free ends of said sidearms, piv oted clamps carried by said plate, a llask centered npom saidsupport and removably held by said clamps and means carried by saidelevator arms for inverting said pattern support and flask.

In testimony whereof I ailix my signature in the pres ence of twowitnesses.
